How many energy storage projects are in Chile?

Currently, 36 of the 129 large-scale projects Latin America projects with an energy storage component under development are in Chile, including 32 out of 71 of the region’s early works projects. The storage technologies either in use or being considered include:

How much battery storage capacity does Chile have?

According to data from Acera, the Chilean Renewable Energy Association, there are only 64MW of battery storage capacity currently active, representing 0.2% of national capacity. AES Andes, a subsidiary of U.S. company AES Corp. operates all 64MW at their Angamos and Los Andes substations.

What kind of energy does Chile use?

Chile has the potential to run exclusively on renewable generation, with an estimated energy mix of 46% solar, 31% wind, 12% hydroelectric, and 8% flexible natural gas power plants, as well as 23% of battery storage capacity. The remaining 2% is split between biomass, geothermal, and other less common energy sources.

Are battery energy storage systems a viable alternative for Chilean power producers?

With transmission lines at overcapacity and permitting delays slowing the development of new grid infrastructure, battery energy storage systems (BESS) have surged as a profitable alternative for Chilean power producers.

How long does a battery last in Chile?

Moreover, the lack of an ancillary services market in Chile discourages shorter duration batteries (1-2 hours) as seen in the US and Europe. The general industry consensus is to maximize the availability of the battery and focus on 2-3 revenue streams instead of 4 to 5 (e.g., energy arbitrage, capacity payment, and frequency reserve).

How much energy does Chile need to replace coal?

In addition, Chile will need an estimated 9.5GW of new flexible capacity over the next decade to fully replace coal and to achieve a significant drop in emissions necessary to meet the government’s climate goals.
